' A J/ME: P. 50K/ 5. BY l ATTORNEY Patented Aug. 5, 1941 UNITED STAT g OFFICE 7 Claims.

This invention relates to Ventilating means for vehicles such as automobiles, and more particularly to a window construction wherein the Ventilating means are formed as a part of the window frame assembly; and has for its object to' provide a form of Ventilating means which is simple and eiiicient in both construction and operation and wherein an elongated opening providing for considerable capacity of air flow is effectively shrouded in a manner obviating disadvantages Which might ordinarily be expected from such an opening while its air ow characteristics are maintained.

The invention also contemplates the arrangement of baffle or deflector means in a manner directing air flow to meet the desirable requirements and promote Ventilating efficiency in the device; the invention further contemplating the arrangement of said baiile means exterior to the window, when used in connection with a window, in such manner that the opening of the window will not be interfered with and will serve as a means of regulating the action of the ventilator.

Still further the invention contemplates the provision of the Ventilator having characteristics of form designed to avoid noises or whistling such as is commonly attendant on the use of louvres and similar means heretofore suggested for the Ventilating of moving vehicles.

A further object is to provide a horizontally elongated Ventilating opening having a cowl or scoop-shaped member extending over one end of said opening and a hood extending therefrom longitudinally above the opening; and still iurther it is an object of the invention to provide such a construction by the simple cutting away of the lower or underside of a horizontally elongated bulge formed in a vehicle wall, as for instance in the sheeting of a window frame the bulge being cut away on its underside throughout the greater portion of its length.

Still further objects subsidiary to the aforesaid objects, or resulting from the construction or operation of the invention as it may be carried into effect, will become apparent as the said invention is hereinafter further described.

In carrying the said invention into effect I may provide the novel construction and arrangement of parts illustrated, by Way of example, in the accompanying drawings, wherein:

Figure 1 is a fragmentary elevation of the upper part of a vehicle door panel embodying the said invention, part of the metal facing being broken away;

Figure 2 is a detail cross section on the same taken on a plane indicated by the line 2-2 in Figure 1;

Figure 3 is a sectional plan of the same taken on a plane indicated by the line 3-3 in Figure 2;

Figure fi indicates an enlargened fragment of the side Wall of a vehicle or enclosure provided with a modified form of Ventilating means including features of this invention;

Figure 5 is a plan of underside of the ventilating means of Fig. 4, the wall being shown in section taken on a plane indicated by the line 5--5 in Figure 4; and

Figure 6 is a detail cross section of the same taken on a plane indicated by the line 6--6 in Figure 4.

Figure '7 is a side elevation of a door equipped with a rotatable window and also with another modification of my invention,

Figure 8 is a Verticalsection taken along the line 8 8 of Fig. '7,

Figure 9 is a side elevation of another type of automobile window having a vertical and transversely sliding window in combination with a still further modification of my invention,

Figure 10 is a horizontal section taken along the line IIi-I 0 of Fig. 9, and

Figure 11 is a section similar to Fig. 10 showing a modiiied arrangement of the screen.

Similar ycharacters of reference indicate similar parts in the several figures of the drawings.

Referring iirst to Figures i, 2 and 3. 1 are the usual sash posts of the vehicle door structure, and 8 the top rail, the interior faces of which are provided with suitably formed channels 9 and IIJ as guides and sealing means for the vertically adjustable glass window II, as will readily be understood Without further detailed description.

The door structure is faced with sheet metal extending at I2 over the posts 'I and also eX- tending at I4 over the face of the top rail 8 and extending materially below the lower edge of the said top rail, as at I5, and terminating in the inwardly turning flange or bead I6, so that when the window is closed the said portions I5 and I6 of the sheet metal member I4 materially overlap the upper marginal portion of the window II forming a chamber II behind the said portion I5.

The metal of the portion I5 is shown as being bulged outwardly, the bulge being of an elongated ovate or so-called streamlined configuration and the under portion of the bulged metal cut away, from one end of the bulge to a point somewhat remote from the other end thereof, to provide an opening therein above which opening the bulged metal forms a hood i8. One end of this hood extends downwardly in a rounded cowl or deilector I9 deilning one end of the said hooded opening.

I prefer to mount, in or over the space in the metal formed by the pressing out of the bulge, a screen 2E) of suitable mesh; and it is also proposed to provide in the chamber il a baille plate 2i extending from one end oi the said bulge portion inwardly toward the plane of the Window and of a length and depth suitable to prevent direct passage of air through the said opening into or from the vehicle, as the case may be, when the window is opened to a suihcient extent to permit any passage of air through the said opening into or from the vehicle.

The bead i6 is also spaced below the lower edge of the said baille plate, and turning inwardly operates as an air deilector cooperating in promoting the respirating or Ventilating functions of the arrangement described.

According to the direction in which the vehicle moves, the cowl i9 operates either to trap and direct air inwardly through the screen to the vehicle or promote a suction causing a ow of air through the screen in the opposite direction as will be Well understood, both of which functions serve effectively to insure ventilation in a structure such as of a vehicle which is not completely air tight.

In Figures 4, 5 and 6, t2 indicates any wall of the vehicle such as a side panel in which the bulge iii may be formed as previously describeL in this case the deilector l5 shown in the previous example may be omitted.

In Figures 7 and 8 my invention is illustrated as applied to a door having a vertically movable window section 3Q and a window section d@ movable vertically and also rotatable about an axis 23. My invention is adaptable for combination with and will considerably enhance the Ventilating qualities of such a window. The window sections 39 and fi@ slide vertically in the channel walls 2t and 25 of the sash post 26B. The sheet metal facing 2 is formed similarly to that aforedescribed, being bulged at 28 with the lower or underneath portion 29 thereof being partially cut away and hooded at its front end 3Q. A screen 3l is inserted interiorly thereof and behind the screen is a deilector 32 which extends from a point slightly forwardly of the hooded end 333 to a point slightly rearwardly of the trailing edge of the bulged portion.

In Figures 9 and if) my invention is illustrated as applied to a diierent type of door. In this case the window 33 is movable vertically in its sash 313 for normal sliding motions and when in closed position it may be moved laterally. The bulged portion 35 of the metallic sash covering Si: is placed vertically so that lateral move-- ment of the window uncovers the interior of the vehicle to the chamber 37 and hence to the exterior of the vehicle through the screen 33.

In Figure 10 the screen 33 is illustrated as being in the plane of the main portion of the covering 35 whereas in Fig. ll the screen @to is illustrated as being normal thereto, in which case it might preferably be made as a chromium plated grill rather than as a screen.

This invention may be developed within the scope of the following claims without departing from the essential features of the said invention, and it is desired that the specication and drawings be read as being merely illustrative and not in a limiting sense, except as necessitated by the prior art.

What I claim is:
